I've added support to for optional chimes and hour-strokes at the top of the hour.

That sort of begs the question as to how to enable/disable the chimes temporarily when you don't want them.

The DIP switches would seem the natural mechanism, but there are only four of them, and I don't want to just keep piling them on.

It occurred to me this morning that I could simply add a config file to the top level of the SD card. That would allow configuration of, say, 8 different timezone/DST settings with the DIP switches and set one switch aside to turn the chimes on and off.

EDIT: The chimes now can actually be on any minute you like, with optional per-hour STROKES at the top of the hour. The SD card now comes programmed to perform full-on Westminster Quarters.
